Designed for ease of use on the site !
The HAND STRAP fits the device neatly to the hand
Prevents careless mistakes
■Auto-power off to conserve battery life
■Non-fuse type protects up to 600V AC
Even if voltage is mistakenly
The HAND STRAP not only prevents the
device from being dropped when working,
but also effectively imparts strength when
parting crowded wiring to clamp.
NOT
applied to the resistance range,
the internal excessive voltage
protection element (PTC
thermister) protects the circuits

NEEDED
for up to 600 V AC.

WARNING
Inspect the unit and check that it is operating correctly before use. When carrying out
measurement on live lines, wear proper protective gear, insulating rubber gloves, insulating rubber
boots and safety helmet, and use extreme caution to avoid electric shock accidents.

DANGER
1. In order to prevent short-circuits and injury, use the clamp product on electrical
circuits with a voltage less than the maximum operation circuit voltage.
2. In order to prevent short-circuits and injury when the clamp core tip is open, do
not use bare conductors.
